16-Cavity Plastic Bottle Cap Injection Mold: Optimal Efficiency for Medium-Scale Production


SHUANGHAO Machinery proudly presents our 16-Cavity Plastic Bottle Cap Injection Mold—a precision-engineered tooling solution designed specifically for manufacturers requiring efficient, reliable cap production at medium volumes. The 16-cavity configuration represents an ideal balance between productivity and flexibility, making it a popular choice for regional bottlers, contract manufacturers, and companies with diverse product lines .

Key Features

1. Optimal Cavity Configuration

Our 16-cavity mold delivers approximately 30% faster production output compared to 8 or 12-cavity configurations, significantly boosting manufacturing efficiency . This design enables simultaneous production of 16 identical caps per cycle, maximizing throughput while maintaining consistent quality across all cavities.

2. Flexible Runner System Options

SHUANGHAO offers both hot runner and cold runner configurations to match your specific production requirements :

Runner TypeAdvantagesBest Application
Hot RunnerNo runner waste, faster cycles, 100% material utilizationHigh-volume production, long-term cost savings
Cold RunnerLower initial investment, simpler design, easier maintenanceSmall to medium production runs, budget-conscious operations

3. Premium Material Construction

Built for extended mold life and consistent performance :

  • Core and cavity inserts: S136 stainless steel with HRC 48-52 hardness for exceptional wear resistance 

  • Core sleeve: DC11 or equivalent with HRC 60-62 for enhanced durability 

  • Mold base: P20 pre-hardened steel ensuring structural integrity 

  • Hot runner components: H13 tool steel with advanced temperature control

  • Mold life: Engineered for 500,000 to 2+ million injection cycles with proper maintenance 

4. Precision Engineering

  • Micron-level accuracy: Advanced CNC machining ensures critical dimensions are maintained within tight tolerances 

  • Superior surface finishing: Mirror-polished cavity surfaces for smooth cap ejection and premium appearance 

  • Interchangeable components: Standardized parts enabling easy maintenance and replacement 

5. Optimized Cooling System

Efficient cooling is essential for fast cycle times and consistent cap quality:

  • Strategically designed cooling channels ensuring uniform heat extraction across all cavities 

  • Enhanced cooling in critical areas such as thread-forming regions and sealing surfaces

  • Balanced temperature distribution minimizing warpage and ensuring dimensional stability

6. Versatile Cap Type Compatibility

SHUANGHAO's 16-cavity molds accommodate a wide range of cap designs :

  • Screw caps and threaded closures

  • Flip-top caps with living hinges

  • Sports caps and push-pull closures

  • Child-resistant closures

  • Dispensing caps and spout caps

  • Custom designs for specific applications
